What Is Disk Caching In After Effects?
Before we dive into the pros and cons of emptying the disk cache, it’s essential to understand what disk caching is and how it works in After Effects. Disk caching is a feature that allows After Effects to temporarily store rendered frames and compositions on your hard drive, rather than only keeping them in RAM. This process is designed to improve performance, reduce rendering times, and enhance overall system efficiency.
When you work on a project in After Effects, the software continuously renders and processes your work, storing the results in the disk cache. This cache is stored on your hard drive, usually in the same folder where your project file is located. The disk cache contains a vast amount of data, including:
- Rendered frames
- Composition files
- Effect data
- Animation cache
- And other temporary files
The disk cache serves as a buffer, allowing After Effects to quickly retrieve and reuse previously rendered frames and compositions, rather than re-rendering them from scratch every time you make changes to your project. This can significantly reduce rendering times, especially when working with complex projects or high-resolution media.
The Benefits Of Disk Caching
The primary advantage of disk caching is improved performance. By storing rendered frames and compositions on your hard drive, After Effects can:
